【題目】We brush our teeth daily, but do you know everything you need to know about dental care and hygiene? Believe it or not, there is a lot more than most people realize. Luckily, here are several apps that can help you.

●Brush DJ

You should brush your teeth for full two minutes as recommended by dentists, but that time can be difficult to judge. Many recommend you listen to music, because many songs are just around two minutes in length. Brush DJ has loads of great tunes that will get you into the twominute habit. There are both songs to listen to, and videos to watch, and you'll find a variety of awesome tunes.

●Orasphere

It's recommended that Orasphere videos be used by dentists for their patients, so they can learn about procedures. Those who do use these videos say that the software can greatly decrease the amount of time it takes to explain procedures to patients.

●American Dental Association(ADA)

Everything you ever wanted to know about your teeth, and then some, can be found on the American Dental Association(ADA) website. You'll find loads of great articles that have the latest news about dentistry（牙科）. Those interested in dental careers will find plenty of information to head them in the right direction, and there's even a section devoted to public dental programs, including Give Kids a Smile and Fluoride in Water.

●DDS GP

Here is more presentation software that explains all types of dental procedures. This is helpful for dentists to have, because they can better explain procedures to their patients.

●Dentistry IQ

【解析】這篇短文介紹了幾種關(guān)于牙齒以及牙科知識的應(yīng)用。

【1】C

細(xì)節(jié)理解題。根據(jù)Brush DJ中的“You should brush your teeth for full two minutes as recommended by dentists”可知，牙醫(yī)建議刷牙要刷兩分鐘。B項在文章提到了相關(guān)內(nèi)容，但是不是牙醫(yī)建議的。故選C.

【2】A

細(xì)節(jié)理解題。根據(jù)Orasphere 中的“the software can greatly decrease the amount of time it takes to explain procedures to patients.”可知，這個軟件可以極大地減少向病人解釋程序的時間。故選A.

【3】D

細(xì)節(jié)理解題。根據(jù)American Dental Association(ADA)中的“You'll find loads of great articles that have the latest news about dentistry（牙科）.”可知，從ADA中我們可以獲得很多有用的最新的牙科信息。故選D.

The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington.

Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world's first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings Peale found the animals himself and found a method to make the exhibits more lifelike. The museum's most popular display was the skeleton (骷髏) of a huge, extinct elephant, which Peale unearthed on a New York farm in l801.
Three of Peale's seventeen children were also famous artists. Raphaelle Peale often painted still lives of flowers, fruit, and cheese.

【題目】All of England

In fact, literary landmarks are so common in London that “blue plaques(木牌)” have been introduced to show off well-known literary sites. One of the more interesting plaques can be found at 221B Baker Street-the apartment of famous fictional detective Sherlock Holmes (although we can be pretty sure that he never actually stayed there).

Outside of London, it is possible to take organized tours around the countryside where England best writers grew up. If you join a Charles Dickens or Jane Austen tour, you’ll have the unique opportunity to visit the locations of famous fictional scenes. But to truly experience literature in person, you can visit Stratford-upon-Avon, the birthplace of William Shakespeare, and watch nightly performances of his plays.

Shanghai, China

Shanghai is a really charming city, where — underneath the surface of the city — one can find some real literary treasures. One star of Shanghai literature is LU Xun, a Writer often celebrated as the father of modern Chinese literature, who spent his last nine years in the city. It’s necessary, then, for all Shanghai literary travelers to visit Lu Xun Park, which features a memorial hall dedicated to the great writer.

Another place worth visiting is the old neighborhood of poet Xu Zhimo. Xu is well known for bringing “New Wave” romanticist poetry into Chinese works. Indian poet Rabindranath Tagore once stayed at his home while visiting Shanghai.

Rome, Italy

The English romantic poet John Keats once traveled to Rome in the hope that the Mediterranean air would cure his tuberculosis(肺結(jié)核). It didn’t, and Keats died within three months.

Despite the fact that Keat’s visit was a quick one, Rome has a reminder of it — the Keats-Shelley House. Keats’ former home has been transformed into a small museum, complete with a working library.

What’s more, just across the street is the Antico Caffe Greco, a cafe frequented by famous authors like Charles Dickens, Loud Byron, Henry James, Hans Christian Andersen, Many Shelley...We could go on, but you probably get the idea that this is somewhere any literary traveler has to go.

【1】This passage is mainly about ________ in different places.

A. cultural introduction B. famous poets

C. scenic spots D. literary sites

【2】In England, ________.

A. Shakespeare’s plays are performed anywhere

B. Sherlock Holmes once lived in London for a short time

C. blue plaques are pinned to mark the literary sites

D. June Austen’s former residence is in London

【3】From the second part of the passage, we know ________.

A. Lu Xun Park is mainly made up of his former houses

B. Tagore once visited Xu Zhimo

C. Xu Zhimo created realistic Chinese poetry

D. Lu Xun spent all his lifetime in Shanghai

【4】Antico Caffe Greco is ________.

A. a beautiful and grand construction

B. a museum in honor of John Keats

C. a place providing various collections of poems

D. a cafe which was visited by many authors in history
